Security versus usability.

@liw Security without usability is like building a wall instead of a door. If a valid user can't get in, security has failed.

@liw @dentangle Or if a valid user can get in but it’s so much of a pain that they put tape over the latch on their way out.

@liw
it's me, using the most powerful possible security suite to manage my browser extensions because it's the only bit of the software i was able to parse

@liw Stating the obvious: the question is vague, though one suspects that the point is to answer in a way that both addresses the question and presumes the question's framing.

That said, applying my #manifestation frame, usability is a manifest, immediate, percievable, clear attribute, whilst security is a covert, latent, emergent, and obscure attribute.

In mass markets, immediacy takes precedence. At least until emergent benefits become realised. Though often only for as long as those rapidly-fading memories persist.

@liw
Confidentiality, Integrity and Availability are the basics of security. Usability is part of it. The idea that security is simply about blocking access is a common misunderstanding.

@liw And the winning answer to Lars's security quiz wasn't my pick, though I think in fairness it is a good answer.

"No security without usability."

@liw No usability without security - a sufficiently predictable system is neither a weird machine nor a user interaction nightmare; weird machines are always user interaction nightmares if you trigger an edge case.
